Walmart apparently sent a memo to store managers on Sept. 19. announcing plans to stop selling Amazon’s line of Kindle products.

“We have recently made the business decision to not carry Amazon tablets and eReaders beyond our existing inventory and purchase commitments,” said Walmart in the memo. “This includes all Amazon Kindle models current and recently announced.”

Reuters, which cited the memo and an unidentified source “familiar with situation,” first reported the news:

In the memo, Wal-Mart said the decision was consistent with its overall merchandising strategy. While Wal-Mart dwarfs other retailers in overall sales, it trails Amazon and others online and has been stepping up efforts to increase its presence there. Consumers who buy Kindle tablets such as the new Kindle Fire HD can shop on the devices for more than just digital books, pushing Amazon into further competition with stores.

The publication did not provide additional details, but Walmart.com currently reflects the reported change. When searching for “Kindle” on the national retailer’s website, no Kindle-related products appear in the queue. It is unclear if Walmart’s website ever offered the tablets, however.

The Kindle Fire HD, a second-generation Kindle Fire tablet available in 7-inch and 8.9-inch form factors, runs a forked version of Android 4.0.

We contacted Walmart and Amazon and will update when more information is available.
